Jim O'Rourke (born January 18, 1969) is an American musician and record producer.[1] He was long associated with the Chicago experimental and improv scene. Around 2000, he relocated to New York before moving on to Tokyo, Japan, where he currently resides.

In the early 1993, O'Rourke formed an avant-rock group with Darin Gray and Dylan Posa called Brise-Glace. The band released one studio album, When in Vanitas..., in 1994. They also released a 7" in the same year titled In Sisters All and Felony/Angels on Installment Plan.

O'Rourke has also released many albums under his own name on a variety of labels exploring a range of electronic and avant-garde styles. His most well-known works may be his series of releases on Drag City, which focus on more traditional songcraft: Bad Timing (1997), Eureka (1999), Insignificance (2001), The Visitor (2009) and Simple Songs (2015). The titles of the first four albums all refer to films by the British director Nicolas Roeg; the first three by direct reference to film titles, the fourth being titled after a fictional album within Roeg's film The Man Who Fell To Earth.
